You Have Questions We Have Answers
Can I expose my “healthy” skin to the light or, do I need to cover it somehow?
It’s usually best to keep uninvolved skin covered with clothing or sunscreen during your treatments, but follow your doctor’s advice. The most important thing about covering “healthy” skin is to be consistent, and always use the same covering techniques on each treatment. (External genitalia should be covered during PUVA therapy.)
If my device is located in a cold room, do I need to allow time for the lamps to warm up?
With a dosimetry machine, there is no real advantage to allowing your machine to warm up first. In situations where a machine is kept in a very cold environment such as a garage, a 5 minute warmup may allow faster treatment times.
I’m seeing good results with my phototherapy treatments other than my face, is it possible the light is working everywhere except for my face?
For best results, make sure that all makeup or anything covering your face has been removed. Additionally, since the face is almost always exposed to light, it may have “photoadapation,” meaning it has become used to this light exposure. Ask your dermatologist if you could benefit from a higher treatment dosage.
How long do I need to wait before I begin to see results?
The length of time varies from patient to patient, and between treatment indications. Typically psoriasis patients will see much faster results than vitiligo patients. The most important thing is to be consistent with your treatments, and to follow your doctor’s treatment plan.
Should I treat for the same amount of time that I treated for in the doctor's office?
Every device has a different level of therapeutic output. Follow your doctor’s directions for dosing advice. If you have questions about how to program your machine to deliver the doses your doctor provides, please contact Daavlin service.
I feel like the unit is not working as well as it used to. Do I need to replace the lamps?
The power of the lamps decrease with use. If your treatments are no longer working, you may need to replace the lamps.
What is a good room to do my treatments in?
Choose a dry, enclosed room where others will not be exposed to the light. Optimum treatment times and lamp life will occur when the machine is kept in a room temperature area that is neither extremely hot nor cold.
My skin turned red after my treatments. What do I do?
Occasional or temporary redness may be normal if it resolves by the next treatment time. If your redness is sustained, ask your doctor if you should reduce your treatment times.
My lamp(s) went out. What do I do?
If your machine’s controller is not turning on, make sure the machine is connected to power and the circuit breaker (if equipped) is turned on. Then, unplug your machine and make sure that the lamps are securely seated in the lamp holders. If only some of the lamps are not working, swap them with the ones that are. If the lamp(s) won’t work at all, you may have a bad lamp(s) and should contact Daavlin customer service.
Can I use my device in different countries?
Every Daavlin phototherapy device has a label near the power inlet with a voltage and frequency specification. If the voltage of the country that you are traveling to matches the label, you can feel free to use it. If you would like to use your device in countries with a different voltage, contact Daavlin for more information. Depending on the exact machine you have, there are a range of possible solutions.
